We're dividing 663656 by 20 
We want to figure out the number of times 663656 can be divided by 20.

Step 1:
When dividing 6 by 20, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 20

Moving on to step 2:
If we divide 66 by 20, we get 3 and a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 60 from 66 leaves us with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 20

Moving on to step 3:
The number 20 fits into 63 3 times, leaving a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 33.0
Subtract 60 from 63 to get 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 20

On to step 4:
The number 20 fits into 36 1 times, leaving a remainder of 16.
The next digit of our result is 1. 
Result so far: 331.0
Subtract 20 from 36 to get 16.
Bring next digit (5) of the dividend behind the 16 and repeat the process: 165 / 20

Step 5:
20 can be fit into 165 8 times, resulting in a remainder of 5.
Put 8 as the next digit of the answer. 
Result so far: 3318.0
The remainder is 5 after subtracting 160 from 165.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 20

On to step 6:
20 goes into 56 2 times with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 33182.0
Deduct 40 from 56 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 7:
20 can be fit into 160 8 times, resulting in a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 33182.8
If we take 160 away from 160, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 33182.8
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 33182.8
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 33182.8 with a balance of 0.0.
